HAROLD M. SGHEIBE, O13 BELMONT, MASSACHUSETTS PUSH-PLATE j Application filed. January 30, 1930. Serial No. 424,618. g

This invention relates to push plates for Y use upon doors to protect the paint or finish and aims to provide a novel plate for that and similar purposes having, among others, the advantages hereinafter described.

In the drawings of one embodiment of my invention described and illustrated herein,

Fig. 1 is a plan; Fig. 2, a vertical section, broken away, on an enlarged scale on the line 22, Fig. 1;

Fig. 3, a side elevation of the washer on an enlarged scale; and

Fig. 4, a bottom view of the washer. My novel push plate comprises, Fig. 1, a suitable plate 1 of glass or similar material and suitable size, provided with one or more passages 2 for locking it to the door or other support.

To give the plate a more finished appearance it is preferred to use oval or round head screws, but to permit the use of fiat head screws without the necessity of bevelling the edge of the passage 2, Fig. 2, the latter is preferably drilled through the plate 1, and then counterdrilled at 3, a portion of its length from the top leaving a shoulder 4, to permit the use of a washer 5.

Heretofore the use of small washers in any connection with similar articles has been attended with considerable inconvenience for the reason that the washers were handled and shipped separately and not inserted in the work at the factory; many washers were lost; and if, by chance, they were inserted in the work at the factory, some of them were sure to fall out and become lost. Furthermore, they were not adapted to be used for both oval or flat head screws.

To obviate the above objections, I have de- 40 vised the novel washer shown, comprising a ring 5 with a tapering neck 6 split to form narrow prongs 7 normally bent inwardly, Fig. 3, and then turned laterally to form the wall engaging members. 7 These prongs are resilient and sharp pointed and the prongs are normally so shaped relative to the top of the washer as to require some pressure to cause them to spring and enter the passage 2 in which they are to be used. At the factory these washers are first centered with and then forced into the passage in the plate, which results in the prongs being turned upwardly somewhat, Fig. 2, and caused to press tightly against the wall Sof the passage. P5

The washers are thus automatically" set when they are forced into the plate, they will bear factory handling, shipping, and handling' again by workmen for installation, without being lost.

This washer of any desired color and size covers'the upper end of the passage 2 and the hole of the washer is sufficiently far within theedge of the passage to readily receive the shoulder of a flat head screw when turned home, with its top flush with the washer top, without danger of cracking the glass, the washer being made of thin material and with ample clearance between its edge and the wall of the passage.

. lVhen the screw is turned home, thepressure therefrom will be distributed upon the plate away from the edge of the passage with no tendency to split the plate. To still further promote this end, the top of the washer is slightly convex so that it may yield somewhat under pressure and carry the pressure, if any, to the plate at a distance from the edge of the passage 2 and thus avoid danger of chipping the edge of the;. plate. 2 i

The neck or prongs, being short, are above the shoulder of the counterbore, and do not extend through the plate to prevent the plate lying flat upon its support. The washer will 5, 35 permit a fiat head or oval'head screw to be turned home substantially level with the washer top, as stated, and if any effort is made to remove the washer, the upturned prong ends will resist the attempt more cited; tually than would the sides of the prongs, and compel the use of substantial force.

My invention is not limited to the particular embodiment thereof described and illustrated.

Claims:

1. An article of the class described comprising a plate of fragile material drilled and coimterdrilled to receive plate locking members, and provided with a self-setting cup;

washer with resilient prongs on its lower face with a spread greater than the diameter of the counterdrilled area, in the counterdrilled area and engaging frictionally the drilled wall to lock the Washer therein and yieldable laterally under pressure of the locking member.

2. An article of manufacture comprising a plate of fragile material having an opening therein, a cup washer in said opening having its neck spaced from the walls of said opening, a flange on one end of the neck of said washer resting on the surface of said plate away from the edge of the opening,and resilient projections extending from said neck into gripping engagement with the walls of said opening to hold the washer therein.

7 3.. An article of manufacture comprising a plate of fragile material having an opening therein, a cup washer in said opening having its neck spaced from the walls of said opening, a flange on one end of said neck resting on the surface of said plate and away from the opening area, and resilient fingers extending outwardly from the other end of said neck and shorter than the depth of the washer receiving opening into yielding and locking engagement with the Walls of said opening. a 4. A cup washer with a tapering neck having a relatively wide flange on one neck end, the neck split longitudinally and forming resilient-prongs on its opposite end outwardly bent and constructed to bend upwardly, and frictionally engage the passage wall when forced therein and yieldahle under pressure of the locking member to increase the grip of the washer prongs against the plate wall.

In testimony whereof, I have signed my name to this specification.
